RPi3 with PXFmini Linux version 4.4.20-v7+ (lander@erle) (gcc version 4.8.3 20140303 (prerelease) (crosstool-NG linaro-1.13.1+bzr2650 - Linaro GCC 2014.03) ) #2 SMP PREEMPT Thu Sep 15 14:06:54 CEST 2016 frambuesa 3 mavros 0.18.3

My remote GCS connects without issue. My topics are not connected and not sure why. Also not sure where it's pulling hardware_id: udp://:6001@ from. I assumed from a launch file but not sure.
